4308H-102-331LF

4308H-102-331LF Description

The 4308H-102-331LF from Bourns Inc. is a high-performance 4-resistor network housed in an 8-pin SIP (Single In-line Package) configuration. Designed for through-hole mounting, this isolated resistor array offers a 330Ω resistance per element with a tight ±2% tolerance, ensuring precision in circuit design. Its compact dimensions (0.784" x 0.085") and 0.350" seated height make it suitable for space-constrained applications. The device operates within a ±100ppm/°C temperature coefficient range, with a resistor-ratio drift of 50ppm/°C, providing stable performance across varying thermal conditions. Rated for 500mW power per element, it is packaged in a tube for secure handling and assembly.
