Product Overview
A boxed mains suppression capacitor in a light grey case, printed with a wheel-in-a-square maker logo and the type designation KNB1530, the value 0,47 uF +/- 10% in the European comma notation, 250V AC, the climatic code 25/085/21, and at the right of the face MKP, X2 and HPF. Below that sits a full block of agency marks, DVE in a triangle, an S in a shield, PP1, OVE, S, N, D, Fi, 565-11055, UL 1414 125V, 1283 275V, CSA, a Y in a circle, CE 140-7 and 10.93. Class X2 parts like this one sit directly across live and neutral, which is why the printed rating matters more here than on any other capacitor in the drawer.
Key Features
- Capacitance 0.47 uF, +/- 10 percent, both printed on the body
- 250V AC, read exactly as marked; Iskra's current catalogue lists KNB1530 at 275 and 300 V AC, but this is an older run and we do not substitute a higher figure for the one printed on a mains-rated part
- Class X2, printed on the body. X2 is the across-the-line class between mains conductors, with a 2.5 kV impulse withstand per IEC 60384-14 (published class definition, not a measurement)
- MKP printed on the body, the published notation for metallized polypropylene film (per Vishay's MKP 1845 data)
- KNB1530 is Iskra's published series designation for a metallized polypropylene RFI suppression capacitor, Class X2, +/- 10 percent above 0.1 uF, to IEC, UL and CSA 60384-14 (per Iskra's published series page)
- Climatic category 25/085/21, quoted as an IEC 60068-1 triple, and the further strings HPF, 565-11055 and 10.93 are quoted as printed and not interpreted
- Light grey rectangular box body, two radial leads from one long edge; no ruler appears in any frame, so no dimension or lead spacing is given
- Verify against Iskra's published KNB1530 series data before designing in.
Applications
- Across-the-line mains filtering between live and neutral
- RFI suppression at the inlet of appliances and power supplies
- Like-for-like replacement of an X2 part of the same value and printed rating
- Motor and switch noise suppression on mains-powered equipment
Frequently Asked Questions
How many should I order? Order the number of positions you are filling plus a spare; 40 are on the shelf. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Can I use this where 275V AC is specified? No. This body prints 250V AC, and that is the rating we sell it at. Iskra's current catalogue shows the KNB1530 series at higher AC ratings, but those figures belong to later production, not to the unit in these photos, and on an across-the-line X2 part you match what is printed on the case.
Every agency that ever inspected this part left its initials on the case, and they all still fit on one face.
