They are not intended to be subject to surface mount processes under any circumstances. The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260C for a period of no more than 10 seconds. Within this time and temperature range, internal temperatures within the converter will not exceed 175C. Care should be taken to control manual soldering limits identical to that of wave soldering. 2 1 Percentage Change In Output Voltage www.murata-ps.com Technical enquiries - email: mk@murata-ps.com, tel: +44 (0)1908 615232 WPN20R.B01 Page 4 of 5 WPN20R 20 Watt Regulated DC/DC Converter USA: UK: France: Japan: Tucson (Az), Tel: (800) 547 2537, email: sales@murata-ps.com Milton Keynes, Tel: +44 (0)1908 615232, email: mk@murata-ps.com Montigny Le Bretonneux, Tel: +33 (0)1 34 60 01 01, email: france@murata-ps.com Tokyo, Tel: 3-3779-1031, email: sales_tokyo@murata-ps.com Osaka, Tel: 6-6354-2025, email: sales_osaka@murata-ps.com Website: www.murata-ps.jp Shanghai, Tel: +86 215 027 3678, email: shanghai@murata-ps.com Guangzhou, Tel: +86 208 221 8066, email: guangzhou@murata-ps.com Canada: Toronto, Tel: (866) 740 1232, email: toronto@murata-ps.com Murata Power Solutions, Inc. 11 Cabot Boulevard, Mansfield, MA 02048-1151 U.S.A.
