CRC3A4E49R9FT

CRC3A4E49R9FT Description

The CRC3A4E49R9FT from KYOCERA AVX is a high-precision 4-resistor array designed for surface-mount applications in compact electronic circuits. Part of the CRC series, this 1206 (3216 Metric) convex package features long-side terminals for improved mechanical stability and solderability. With a 49.9Ω resistance per element, ±1% tolerance, and ±100ppm/°C temperature coefficient, it delivers stable performance across varying environmental conditions. The isolated circuit type ensures minimal crosstalk, making it suitable for signal integrity-critical designs. Rated at 62.5mW power per element, it operates reliably in low-to-moderate power applications. The obsolete status indicates legacy compatibility, while REACH Unaffected and MSL 1 (Unlimited) certifications ensure environmental and handling robustness.
