We do not offer free samples for custom components due to the engineering time and material costs involved. However, standard product samples may be provided free of charge, with shipping costs to be covered by the requester.
We recommend using our Custom Online Quote Form to clearly communicate your specifications. Based on your input, we provide either a Ballpark Estimate (typically within 1–2 business days) or a Firm Quotation (usually within one week).
- Firm Quotation:
Requires detailed engineering analysis, including multiple design iterations to meet your electrical and mechanical requirements. Our team prepares layout drawings, BOMs, labor instructions, and custom material specs. Operations then verify manufacturability, and Purchasing assesses material costs and lead times from our supplier network. A formal quotation is then issued, including unit pricing, NRE/tooling charges (if applicable), and lead time. - Ballpark Estimate:
A preliminary cost estimate based on similar designs from our extensive database. This is useful for early-stage budgeting or bid submissions. It does not include lead time or minimum material purchase requirements.
An NRE charge is a one-time fee that covers the engineering and setup work required to design and prototype a new custom magnetic component. It includes:
- Design: Preparing manufacturing documents such as drawings, BOMs, and labor routings.
- Set-Up: Assisting production with equipment and tooling setup.
- Build: Additional labor and materials for the initial build.
- Evaluation: Testing and quality checks to verify the prototype.
This charge may be amortized—that is, spread across the unit cost—or waived if a bulk production order is placed.
We strive to meet your requested delivery date. Standard samples are often available from stock and can be shipped promptly. For non-stock or custom items, lead time may extend by a few business days, especially if special materials are required.
Once a quote is approved, the project is routed through key departments to ensure a successful build. The process includes:
- Evaluation Report: The designer issues a report confirming the prototype meets your requirements and internal specifications.
- Design Review: Engineering reviews the design and prepares formal manufacturing instructions.
- Material Procurement & Scheduling: Materials are ordered, and production is scheduled.
- Prototype Build: Our manufacturing team assembles the prototype under engineering supervision.
- Quality Assurance: A first-article inspection is conducted to verify conformance.
We support blanket orders with competitive pricing for scheduled releases. To facilitate this, the following terms apply:
- Order Term:
Blanket orders can be scheduled for up to 8 months. We typically purchase custom raw materials upfront to reduce costs and hold them for the order duration. Extended inventory holding affects cash flow, so we request adherence to agreed schedules. - Safety Stock:
We can maintain agreed quantities of finished parts as safety stock for up to 10 weeks. After this period, parts must be shipped and invoiced. A 4-week lead time is required to replenish stock after each release. - Extended Finished Goods Storage:
If you request inventory holding beyond scheduled shipment, we offer warehousing for up to 3 months at a 1.5% monthly holding fee (prorated daily from the original ship date). After 3 months, the parts must be shipped and invoiced. - Raw Material Holding:
We can hold raw materials for up to 4 months. Beyond this, we’ll continue storage but will issue an invoice for the material cost.
These terms enable us to offer favorable pricing for long-term, high-volume commitments while ensuring supply chain efficiency.
We are flexible with shipping arrangements and can use your preferred carrier. Our experienced logistics team can assist with customs, import/export documentation, and international air freight coordination. We work with major logistics providers, including FedEx, DTDC, Delhivery, and others as needed.
Our standard delivery term is Ex Works (EXW).
For domestic shipments within India, please provide:
- Contact name of the person managing your shipping
- Accurate ship-to address (if different from billing)
- Active 15-digit GSTIN
- Preferred courier and freight account number
For international shipments:
We coordinate with you during order placement to arrange the most efficient and cost-effective shipping solution.
While we commonly use FedEx and DHL for international freight, we can ship via any carrier per your requirements.

In India, standard mains power is 240V at 50 Hz, but the required input voltage and frequency may vary depending on the specific application or upstream circuitry. Shreejee Electronics can manufacture transformers for nearly any voltage and frequency specification.
Yes. If specifications are unknown, we can often assist by analyzing a non-functional unit. Customers frequently send us the original transformer, which we disassemble to accurately determine its design parameters. Device schematics are helpful but not always sufficient. Please contact us to explore your options.
All components undergo rigorous inspection and testing at multiple stages during and after production. Prototypes receive additional evaluation by both the design engineer and quality assurance specialists to ensure compliance with your specifications and our internal standards.
No prototype or custom part is shipped without meeting all quality criteria and is accompanied by a Certificate of Compliance upon request.
We perform 100% testing of all products in accordance with your specifications. The specific tests conducted depend on the transformer type and application requirements. Our testing capabilities include, but are not limited to:
- Continuity
- Excitation (Magnetizing) Current
- Winding Inductance
- Leakage Inductance
- Winding Resistance
- Open-Circuit and Loaded-Circuit Voltage
- Turns Ratio
- Dielectric Strength (HiPot)
- Quality Factor (Q)
- Interwinding Capacitance
- Insulation Resistance
For more information, check out our capabilities in detail.
Yes. We can manufacture transformers in full compliance with the RoHS Directive upon request. For details, please refer to our official RoHS Compliance Statement.
Yes. If you provide your electrical specifications and dimensional constraints, we can design a transformer to meet both. We typically offer a reliable estimate of the final dimensions required to achieve your performance targets.
It depends on the target region. Transformers designed for 60 Hz systems (e.g., North America) may require redesign for 50 Hz regions such as India or Europe. Operating a 60 Hz transformer at 50 Hz without modification can lead to overheating. Additionally, a 50 Hz design generally requires about 20% more core volume, which increases size.
Depending on your circumstances, we offer multiple easy ways to pay for parts. Please get in touch with us for more information.
