CAY16-222J4LF – BOURNS

Overview

The Bourns CAY16-222J4LF is a high-density, 4-element isolated resistor array designed for precise signal conditioning and impedance matching in compact electronic systems. Its core strength lies in providing consistent 2.2 kOhm resistance values with a tight 5% tolerance across a broad -55°C to +125°C operating range, crucial for maintaining signal integrity in demanding environments. A key design consideration is the trade-off between element power dissipation (62.5 mW) and the total package power (250 mW); engineers must carefully manage thermal dissipation to prevent derating and ensure long-term reliability, especially in densely populated PCBs where heat can accumulate.
