Epson

The Epson profiles in this catalog are its 32.768 kHz tuning-fork crystals — the watch-frequency parts behind real-time clocks in meters, appliances and wearables. The selection spans Epson's three miniature case lines: the FC-135 at 3.2 x 1.5 mm, the FC-12M at 2.05 x 1.2 mm and the FC1610AN at 1.65 x 1.05 mm. The load value is the detail to buy carefully: a tuning-fork crystal only runs at its marked frequency into the load capacitance it was specified for, and Epson sells the same case under different codes for different loads — two of the FC-135 profiles here differ in nothing else. Tolerance, ESR and drive level are likewise per-code figures from Epson's own part-number database, where each profile here was verified. Match the complete Epson code, including the load suffix, in your RFQ and we will reconfirm the offered lot against Epson's records before quoting.

Sourcing notes for Epson parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
