Ceramic Capacitor 90pF 560V 561K 5pcs

The Ceramic Capacitor 90pF 560V 561K sold here is a 561K metal oxide varistor (MOV), supplied in a pack of 5. It looks like a ceramic disc capacitor, but it works as a voltage-dependent resistor: below about 560 V it passes almost no current, and above that its resistance drops sharply so it clamps surges and spikes. With a 350 V AC continuous rating, the 561K suits higher-voltage AC lines and DC circuits up to 460 V, and gives 230–240 V mains equipment a large margin against voltage swells.

Ceramic Capacitor 90pF 560V 561K Varistor Specifications

• Component type: metal oxide varistor (MOV), disc type with two leads
• Marking code: 561K (56 × 10¹ = 560 V, K = ±10%)
• Varistor voltage: 560 V ±10% (about 504–616 V), measured at 1 mA DC
• Maximum continuous voltage: 350 V AC or 460 V DC
• Capacitance (as listed): 90 pF
• Polarity: none, works in both directions
• Pack size: 5 pieces

561K Varistor Applications

• AC lines and equipment up to 350 V AC
• 230–240 V mains circuits that see large voltage swings
• DC links of rectified 230 V mains (about 325 V DC) in power supplies, motor drives and inverters
• Spike suppression across motors and contactor coils
• Industrial control panels and electronics repairs

What's in the Box

• 5 × 561K metal oxide varistors

Tip: A higher-voltage varistor survives swells better but clamps spikes at a higher level, so for most 230 V equipment a 431K or 471K protects more closely; use the 561K where the supply runs high or the circuit needs the extra margin. Fit it after a fuse and work only with the power off.
