CRB2A4E681JT

CRB2A4E681JT Description

The CRB2A4E681JT from KYOCERA AVX is a compact, surface-mount resistor network designed for high-density PCB applications. Part of the CRB series, this 4-resistor array features isolated 680Ω resistors with a ±5% tolerance and a ±250ppm/°C temperature coefficient. Encased in an 0804 concave package (2.00mm x 1.00mm x 0.50mm), it offers a power rating of 62.5mW per element and is supplied in tape-and-reel packaging for automated assembly. With long-side terminals and an MSL 1 (unlimited) moisture sensitivity rating, it ensures reliability in diverse environments.

CRB2A4E681JT Features

• Space-Saving Design: Ultra-low profile (0.50mm height) and compact 0804 footprint optimize board space.
• Stable Performance: ±250ppm/°C temperature coefficient ensures minimal resistance drift under thermal stress.
• High Reliability: REACH-compliant and EAR99-classified, suitable for industrial and consumer applications.
• Ease of Assembly: Tape-and-reel packaging and surface-mount compatibility streamline high-volume production.
• Isolated Circuitry: Independent resistors (4x 680Ω) prevent cross-talk, ideal for precision signal conditioning.
