Resistor Array 102J 8pin 1Kohm

The Resistor Array 102J 8pin 1Kohm is an 8-pin resistor network that combines several 1 kΩ resistors in one compact part. The marking 102J gives the value, 1 kΩ (10 followed by 2 zeros), and the standard tolerance letter J, which means ±5%. One array replaces a row of single resistors, saving board space and soldering when many lines need the same value.

Resistor Array 102J 8pin 1Kohm Specifications

• Resistance: 1 kΩ per resistor (code 102)
• Tolerance code: J, the standard letter for ±5%
• Pins: 8
• Circuit: 8-pin networks are made either bussed, with 7 resistors sharing pin 1, or isolated, with 4 separate resistors; see the tip to check
• Pin 1: usually marked with a dot or line on the body

Resistor Array 102J 8pin 1Kohm Applications

• Current limiting for LED bar graphs and indicator rows (about 3 mA per LED at 5 V)
• Series resistors that protect microcontroller I/O pins
• Stronger pull-ups or pull-downs for noisy or long lines
• Switch and keypad interfaces
• Repairing boards that use resistor networks

What's in the Box

• 1 × 8-pin 1 kΩ resistor array (102J)

Tip: Measure pin 1 to pin 2 and pin 1 to pin 3 with a multimeter. If both read about 1 kΩ, the array is bussed and pin 1 is the common pin; if pin 1 to pin 3 reads open, it is isolated, with resistors on pins 1–2, 3–4, 5–6 and 7–8.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
