IEC colors are used. by a cement coating applied so that terminations remain completely clear. Solvent Resistance The body protection and marking are resistant to all normal This permits a well dened body length, (clean lead to industrial cleaning solvents suitable for printed circuits. clean lead dimension L). Flammability Terminations The resistors coating will not burn or emit incandescent particles Material Solder-coated copper wire. under any condition of applied temperature or power overload. Strength The terminations meet the requirements of IEC 68.2.21 Solderability The terminations meet the requirements of IEC 115-1, Clause 4.17.3.2 Wire and Film Technologies Division 4222 South Staples Street Corpus Christi Texas 78411 USA Telephone: 361 992 7900 Facsimile: 361 992 3377 Website: www.irctt.com MFP Series Issue October 2008 Sheet 2 of 3
