Frequently asked questions
Is a free sample available for this product?
Yes — free samples in reasonable quantities for engineering evaluation, shipped within 2–3 business days. Submit the request via the inquiry form on this page or click 'Request Sample' above. We typically include 5–10 pieces and a printed datasheet.
What is the minimum order quantity?
Standard MOQ is 1,000 pieces. For higher-power product families (resistor cabinets, large aluminum-housed units) MOQ may be lower or per-order. Annual contract pricing available for forecasted volumes — tell us your projected annual usage during the quote stage.
How long is the warranty?
12-month standard warranty from date of shipment, covering defects in materials and workmanship under specified operating conditions (within rated power, ambient ≤70°C, mounting per datasheet). Custom and high-reliability variants can have extended warranty terms specified in the contract.
What payment terms do you accept?
T/T (wire transfer) is most common: 30% advance, 70% before shipment for new customers; net 30 / net 60 for established customers. Letter of Credit (L/C at sight or with usance) accepted for orders >$50,000 USD. PayPal accepted for sample-only orders under $1,000.
Can I order this product in custom dimensions or values?
Yes. Custom resistance values within the platform's range carry no extra cost (just specify in the order). Custom dimensions, mounting holes, terminations or non-standard packages may incur a one-time tooling fee (typically waived for orders >5,000 pieces). See the Customization page or submit drawings via the inquiry form.
How do I get a datasheet or 3D model?
Email info@resistor-factory.cn with the part number — we send PDF datasheet (English) and STEP/IGES 3D model where available, typically within 1 business day. Free, no NDA required for standard products. For custom variants, the model is delivered after the design review meeting.
