Product Overview
The CTS 750-101-R270 is a thick film cermet single in-line package (SIP) resistor network containing 9 individual 270-ohm resistors connected to a common bus on pin 1. Housed in a compact, single-sided 10-pin footprint with standard 0.100-inch (2.54 mm) lead spacing, it saves circuit board area compared to discrete axial resistors while simplifying layout for bus pull-up or pull-down terminations.
Key Features
- 10-pin through-hole single in-line package (SIP)
- Bussed schematic 1 configuration with 9 independent 270 Ω resistors sharing pin 1 as common
- Standard 2.54 mm (0.100 in) pin pitch for standard prototype boards and through-hole PCB layouts
- Thick film cermet construction for stable resistance and durability
- Clear part marking: 750-101-R270Ω CTS8322
Applications
- Logic bus pull-up or pull-down termination on legacy digital computing boards
- Current limiting for 10-segment LED bar graph displays on vintage bench instruments
- Breadboard and stripboard microcomputer builds where tidy bus wiring reduces clutter
- Maintenance and restoration of vintage industrial controllers from the 1980s
Frequently Asked Questions
What circuit configuration does this CTS network use?
This is schematic 1 (bussed), featuring 9 individual 270-ohm resistors that each connect between an isolated pin (pins 2 through 10) and a common bus on pin 1.
What is the lead pitch of this component?
Lead spacing is standard 2.54 mm (0.100 inch) center-to-center, making it directly compatible with standard perfboard, breadboards, and IC sockets.
Why buy individual CTS networks here rather than buying a bulk lot?
Ordering individually allows you to buy the exact count needed for a repair or build without taking on dozens of unneeded surplus parts. When purchasing in quantity, more pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, ship free once the order passes $28, and leave our Idaho warehouse the same or next business day.
Few things clean up a logic board faster than a single in-line bus array that replaces a tangled thicket of discrete resistors. Slot this into your board, solder nine terminations in one line, and keep your layout tidy.
