BC Components Product specification Varistors 2322 592 to 2322 595 FEATURES MARKING MOUNTING • Zinc oxide disc, epoxy coated The varistors are marked with the following information: The varistors are suitable for processing on automatic insertion and cutting and bending equipment. • Straight leads • Straight leads with flange (2322 592 and 593 series only) • Maximum continuous RMS voltage • Kinked leads. • Series number (592, 593, 594 or 595) APPLICATION • Date of manufacture. • Manufacturers logo • Suppression of transients. ORDERING INFORMATION DESCRIPTION The varistors are available in a number of packaging options: The varistors consist of a disc of low-β ceramic material with two tinned solid copper leads. They are coated with a layer of ochre coloured epoxy, which provides electrical, mechanical and climatic protection. The encapsulation is resistant to all cleaning solvents in accordance with “IEC 60068-2-45”. • Bulk • On tape on reel 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 Fig.4. Soldering ≤240 °C; duration ≤5 s. Resistance to heat • On tape in ammopack. The basic ordering code for each option is given in Tables 3, 4 and 5. To complete the catalogue number and to determine the required operating parameters, see Table 7. ≤260 °C; duration ≤5 s. INFLAMMABILITY The varistors are non-flammable.

The sinusoidal voltage is assumed as the normal operating condition. If a non-sinusoidal voltage is present, type selection should be based on multiplying the peak voltage by a factor of 0.707. 2. The voltage measured at 1 mA meets the requirements of “paragraph 4.3 of CECC specification 42000”. The tolerance on the voltage at 1 mA is ±10%. 3. High energy surges are generally of longer duration. The maximum energy for one pulse of 10 × 1000 µs is given as a reference for longer duration pulses. This pulse can be characterised by peak current (Ip) and pulse width t2 (virtual time of half Ip value, following “IEC 60060-2, section 6” ). If Vp is the clamping voltage corresponding to Ip, the energy absorbed in the varistor is determined by the formula: E = K × Vp × Ip × t2 where: K is dependent on the value of t2 when the value of t1 is between 8 µs and 10 µs; see Fig.13. 4. A current wave of 8 × 20 µs (requirement of “paragraph B.2.10.1 of CECC specification 42000” ) is used as a standard for pulse current and clamping voltage ratings. The maximum non-repetitive transient current is given for one pulse applied during the life of the component. 5. Only available on request 6. CECC approved types.
