1624122-8 Description

The 1624122-8 from TE Connectivity Passive Product is a high-precision 4-resistor network designed for demanding surface-mount applications. Encased in a compact 1206 (3216 Metric) convex package with long-side terminals, this obsolete yet reliable component offers a 100Ω resistance per element with a tight ±1% tolerance and an ultra-low ±25ppm/°C temperature coefficient (TCR). Its 62.5mW power rating per resistor and isolated circuit type make it ideal for precision voltage division. The ROHS3-compliant device features a moisture-resistant MSL 1 (Unlimited) rating and comes in a tape & reel (TR) packaging for automated assembly.

1624122-8 Features

• TCR-Matched Resistors: Ensures minimal drift (±25ppm/°C) for stable performance in temperature-sensitive environments.
• Compact & Robust Design: 0.126" x 0.063" (3.20mm x 1.60mm) footprint with a low-profile 0.026" (0.65mm) height, suitable for space-constrained PCBs.
• High Precision: ±1% tolerance and isolated resistors reduce crosstalk, critical for analog signal integrity.
• Industrial-Grade Reliability: Conforms to EAR99 and HTSUS 8533.21.0020 standards, with long-side terminals enhancing mechanical stability.
