2Pin 53mm Single Disc VDR Metal Oxide Varistor MOV Block 53D271K 270V 10% 70KA For UPS Overvoltage Protection
Description
The varistors consist of a disc of low-b ZnO ceramic material with two solid copper leads (S20 types only) or copper clad steel wire. The wires have a matte tin plating. They are coated with a layer of ocher colored halogen-free epoxy, which provides electrical, mechanical and climatic protection. The encapsulation is resistant to all cleaning solvents in accordance with IEC 60068-2-45.
The 53D series radial leaded varistors provides an ideal circuitprotection solution for lower DC voltage applications by offeringhigher surge ratings than ever before available in such smalldiscs.The maximum peak surge current rating can reach up to 70KA(8/20 μs pulse) to protect against high peak surges, includingindirect lightning strike interference, system switching transientsand abnormal fast transients from the power source.

MOUNTING
The varistors are suitable for processing on automatic insertion and cutting and bending equipment.
Varistors with flanged leads provide better positioning on printed-circuit boards (PCB) and more accurate control over component height. This is important for hand mounting and automatic insertion techniques; see outlines of flanged leads drawing.
Typical soldering
235 °C, duration: 5 s (Pb-bearing)
245 °C, duration: 5 s (lead (Pb)-free)
Resistance to soldering heat
260 °C, duration: 10 s max.
INFLAMMABILITY
The varistors are passive non-flammable.
The encapsulation is made of flammable resistant epoxy in accordance with UL 94 V-0.
