Product Overview
Xicon 271-680 Metal Film Resistor - 680 ohm, 1/4 Watt
Condition
The photo show a representative unit from our stock of 840 pieces, sold each. The photographed unit has a light blue cylindrical body with a group of four narrow bands - blue, grey, black, black - toward one end and a separated reddish band toward the other, and long uncut axial leads laid out against the ruler. No printed alphanumeric part marking is visible in these photos. Same or next business day shipping from our Idaho warehouse. Honest pricing, no nonsense. Online since 1999. We are here for our customers, with a no-hassle satisfaction guarantee.
Product Overview
This is the 680 ohm value of Xicon's 271- ordering series, the 1/4 watt metal film axial line Mouser catalogues as MF-RC. We hold these under the ordering number 271-680, sold one piece per unit out of a shelf count of 840. It is the sort of part nobody writes home about: a plain 1 percent bias or pull-down value that sits in a board for twenty years and never asks for anything.
Key Features
- Resistance: 680 ohms, per Mouser's published 271-680 catalogue entry
- Tolerance: 1 percent, per Mouser's published 271 series data
- Power rating: 250 mW (1/4 watt), per Mouser's published 271 series data
- Temperature coefficient: 50 PPM per degree C, per Mouser's published 271 series data
- Operating temperature: -55 degrees C to +155 degrees C, per Mouser's published 271 series data
- Voltage rating: 250 V, per Mouser's published 271 series data
- Composition: metal film - established by the 271 series the stock is held under, not by the photograph
- Body: axial cylindrical, 2.5 mm diameter x 6.8 mm length, per Mouser's published 271 series data
- Mounting: PCB mount, through hole, axial leads
- Verify against Xicon's published 271 series data before designing in.
Applications
- Bias, pull-up and pull-down positions in through-hole analog and logic boards
- Base and gate series resistors in small-signal transistor stages
- LED current limiting on low-voltage rails
- Repair and restoration work where a 1 percent axial part is wanted over a 5 percent substitute
Frequently Asked Questions
Need more than one? More pieces cost less each - the price-break table on this page shows what each quantity costs.
How many should I order?
Order the count your build needs and a few spares - 840 pieces are on the shelf here, so a handful or a run of a few hundred comes out of the same bin. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
How do I confirm the value on the part itself?
You cannot read it off a printed string - the photographed unit carries color bands and no alphanumeric marking. The 680 ohm figure on this page comes from the published 271-680 catalogue entry, which is the ordering number this stock is held under, and we have not decoded the bands to confirm it. Meter one before it goes into a board if the value is critical to the circuit.
Eight hundred and forty of these are on the shelf, and the ruler photo is there because the body is shorter than the word that names it.
