Product Overview
Xicon 270-20K-RC metal film through-hole axial resistors, 20k Ohm, 1/8W power rating, ±1% tolerance, 50 PPM/°C temperature coefficient. This is the full 200-piece bag - the same factory bulk configuration these ship in from the distributor. Metal film construction gives you lower noise and tighter stability than carbon film at the same price point.
Key Features

- Tolerance: ±1%
- Temperature coefficient: 50 PPM/°C
- Construction: Metal film, through-hole axial
- Body: Miniature blue, approx. 3-4mm length per photo measurement
- Leads: Long tinned axial leads, breadboard and PCB ready
- RoHS compliant - confirmed on lot label
- Quantity: 200 pieces per bag
Applications
- Plugging into a breadboard during prototyping when you need a stable 20k pull-up or voltage divider that won't drift
- Replacing noisy carbon composition resistors in vintage audio amplifier signal paths to reduce hiss and improve channel matching
- Setting bias points in transistor and op-amp stages where 1% tolerance keeps the math honest
- Current limiting and input protection on Arduino, Raspberry Pi, and similar microcontroller projects
- Building resistor assortment stock so you're not hunting down a single 20k mid-project
- Sensor interface circuits and analog front ends where 50 PPM/°C stability matters across temperature swings
Frequently Asked Questions
Are these through-hole or surface mount?
Through-hole axial. Long tinned leads pass through holes in a PCB or breadboard and are soldered in place. Not suitable for SMT reflow.
Is 1/8W enough for typical hobbyist and audio repair use?
For most signal-level circuits - pull-ups, voltage dividers, bias networks, audio stages - yes. Calculate the actual power dissipation for your circuit (V²/R or I²R) before placing the resistor. If the result is close to or above 0.125W, use a 1/4W or higher rating instead.
What is the operating temperature range?
-55°C to +155°C.
Is the 270-20K-RC the same as other 20k 1/8W 1% metal film resistors from other brands?
Electrically interchangeable with any 20k Ohm, 1/8W, ±1%, 50 PPM/°C through-hole axial metal film resistor of the same miniature body size. Confirm lead spacing fits your PCB footprint before substituting on a production board.
Two hundred little blue resistors that know exactly what they are - 20k, 1%, steady as a rock. Stack them in a parts drawer and stop improvising on the next build.
