SQS20B1001GSLF

SQS20B1001GSLF Description

The SQS20B1001GSLF from TT Electronics / BI Technologies is a high-density 19-resistor bussed network in a compact 20-pin SSOP package. Designed for surface-mount applications, it features a 1kΩ resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying thermal conditions. The device operates at 100mW power per element and is housed in a 0.341" x 0.154" (8.65mm x 3.90mm) footprint, making it ideal for space-constrained PCB designs. Although marked as Obsolete, it remains a reliable choice for legacy systems due to its REACH Unaffected compliance and Moisture Sensitivity Level (MSL) 1 rating, allowing unlimited floor life.
