The 4310R-102-221 is a 10-pin isolated thick-film molded SIP resistor network manufactured by Bourns, featuring 5 isolated resistors of equal value with a resistance code of 221 (220 ohms). This component incorporates thick-film technology with a low-profile design that provides compatibility with DIPs and automatic insertion equipment, while maintaining superior package integrity. The network operates at a maximum voltage of 100 V, with a power rating of 0.20 watt per resistor at 70°C and a temperature coefficient of resistance of ±100 ppm/°C (for 50 O to 2.2 megaohms). The device is RoHS compliant, features a dielectric withstanding voltage of 10,000 megohms minimum, and meets MIL-STD-202 environmental test requirements including thermal shock and moisture resistance. Common applications include DRAM termination, SCSI networks, and R/2R ladder networks where precision resistor matching and reliability are essential.
