BOM-first conversations
Part numbers, packages, usage and order requirements stay central to the discussion.
From a single hard-to-find part to a multi-line BOM, JELCORE helps turn component requirements into a clear sourcing conversation.

JELCORE is the business brand of Shenzhen Jiexin Technology Co., Ltd. Our reference catalogue covers MCUs, power, analog, memory, protection, passive parts, connectors and sensors.
Any quantities shown in the automotive list are clearly identified as unverified source-sheet snapshots, not live stock. Send your exact part number, target quantity, delivery location and requirements for a project-specific quotation.
Explore eight connected product groups. All listed part numbers come from the JELCORE reference catalogue.
01Microcontrollers & embedded processors
02Regulation & power conversion
03Signal chain & communication
04Flash, EEPROM & DRAM
05Power semiconductors & ESD
06Capacitors, resistors & magnetics
07Board, I/O & interconnect
