Buyer filter

Built for bigger orders, not small retail purchases.

Demand profile Bulk, scheduled or repeat usage

Ideal RFQs include target quantity, monthly consumption, delivery window and approved manufacturers.

Decision profile Engineering and quality approval

We support exact MPN checks, cross references, packaging evidence and qualification constraints.

Market profile China delivery and local urgency

Designed for China-based factories, trading desks and procurement teams managing shortage pressure.

Parts line-card

The categories we actively source.

Use this page as the buyer-facing list. It is broad enough to show capability, but still focused on shortage-risk discrete and power semiconductor demand.

How to send a strong RFQ

Better data gets better stock.

Large buyers get the fastest serious response when the request includes the information needed to separate real stock from risky offers.

Exact MPNs

Manufacturer, full part number, package, grade and approved alternates.

Volume profile

Immediate quantity, monthly usage, target price and delivery schedule.

Quality rules

Date-code limits, CoC needs, AEC-Q, PPAP, RoHS, REACH or factory approvals.

End use

Application, destination, restricted-party screening and compliance constraints.

Ready for China demand

Send your shortage list or AVL demand.

We will review the parts, identify sourcing routes, flag risk and come back with the evidence needed for a serious purchasing decision.
