This document introduces the features and characteristics of Vishay Thin Film PL340 series precision resistor networks. This series of resistors is available in a 20-pin J-lead chip carrier and provides the largest number of resistors in a single surface mount package. In addition to providing excellent TCR tracking and long-term stability within a large multi-resistor network, costs are minimized. These devices are suitable for all industrial applications as well as in military applications where plastic packaging is acceptable. Custom configurations, values, and tolerance combinations are available with fast turnaround.
The PL340 series provides ten isolated resistors, while the PL341 and PL342 series each contain nineteen resistors in a 20‑lead J‑lead plastic chip carrier. All devices offer a resistance range of 500 Ω to 100 kΩ with tight tolerance options and low temperature coefficients.
The document includes a package outline drawing, detailed electrical characteristics, and ordering formats. It is intended for designers needing high‑precision resistor networks for industrial or military applications where plastic packaging is acceptable.
