Part family

How to buy oscillators in small lots from the United States

Send a requirement list with the oscillator part numbers and quantities. Each line is sourced to order from authorized US distributors and consolidated with the rest of your list into one shipment and one customs entry. Gatewell USA sources and fulfills genuine electronic components from authorized US distributors, to order.

On the line card this family reads: oscillators from SiTime, NDK and Abracon. Those are representative parts. Requirement lists are quoted line by line.

The buyers are integrators, repair and overhaul shops and contract manufacturers buying mixed small lots. We serve the United Arab Emirates, Saudi Arabia and the Gulf, Türkiye, Central Asia, the Caucasus, Singapore, Malaysia, Thailand, Vietnam, Indonesia, the Philippines and the United States, from Los Angeles, California.

Some parts in this family are carried in a small stocked position and are marked in stock on their part pages. Everything else on the Timing list is sourced to order.

What we source in this family and how your list is quoted

Timing parts are sourced to order. Lead time follows the distributor's stock position and is stated on the quote.

A family name is not a classification. Package variants of one base part can carry different classifications. The part number on your line is the one we classify and the one we quote.

The quote is cost-plus. It is built line by line from distributor cost, inbound freight, outbound freight, cargo insurance and any duties or fees we pay, plus the margin.

When a line requires a US export license, we file for it and quote it subject to approval. Ask us.

What you supply and what we file

Four fields per line: MPN, quantity, target date and deliver-to address.

Wire and ACH accepted; other arrangements by written agreement.

We handle the US export filing. Tracking and documents reach you the day the shipment moves. Import formalities, duties and taxes at destination are yours. We supply the commercial invoice grouped by tariff line, the packing list, the certificates and the export filing citation.

What ships and the provenance pack

Parts are received and inspected before they are packed. Date and lot codes are photographed. Labels are scanned. Moisture barrier bags are checked. Counts and weights are checked against the packing slip. Then the lot is labeled, packed and documented.

Every lot ships with a provenance pack: the distributor's packing slip and the manufacturer or distributor certificate of conformance. A distributor invoice copy with prices redacted, date code photographs and label scans are sent on request. Moisture barrier bags ship sealed as received, or resealed with fresh desiccant and a humidity indicator card inside floor life.

Timing lines travel with the rest of your list. FPGAs, converters and interface parts on the same requirement list ship in the same consignment, under one commercial invoice grouped by tariff line.

How a request is built on the site

Build the request on the site or paste a BOM. Each line carries the four fields.

The requirement list is logged with a reference. A cost-plus quote comes back by email.

Accept the quote and a proforma invoice follows, grouped by tariff line. A new buyer prepays the first order in full. After the first order the deposit covers landed cost and the balance falls due on delivery confirmation. The distributor order is placed once funds have cleared.

You can also send the list to requests@gatewellusa.com or call (213) 558-2728. Gatewell USA, 811 W 7th Street, Suite 900, Los Angeles, CA 90017.

Questions

Can I give you a frequency and a package instead of a part number?

Send the orderable part number. A family name is not a classification. Package variants of one base part can carry different classifications.

Are two frequencies from the same oscillator series one line or two?

Two. Each orderable part number is its own line on the quote.

Requirement lists are quoted line by line, at the quantity on each line.

Can oscillators ship with the FPGAs and converters on the same list?

Yes. Many lines are consolidated into one shipment and one customs entry.

The commercial invoice is grouped by tariff line. One requirement list becomes one consignment.

What if the oscillator I need is not on the line card?

Put it on the requirement list. The line card lists representative families and representative parts.

Requirement lists are quoted line by line.

How is lead time communicated?

Lead time follows the distributor's stock position and is stated on the quote. The quote runs line by line. Each part number on your list carries its own answer.

How are moisture-sensitive oscillators packed?

Moisture barrier bags ship sealed as received, or resealed with fresh desiccant and a humidity indicator card inside floor life.

Bags are checked at receiving inspection, along with date and lot codes, labels, and counts and weights against the packing slip.

What is the end-user statement?

A statement naming who will use the parts. Most orders need none. When a line needs a US export license, we tell you what the application requires.
