Surface Mount parts are packaged in a Moisture Barrier Bag (MBB) with a Humidity Indicator Card and desiccant to ensure solderability. The MBB is marked with a Moisture-Sensitive Identification Label. Ordering Information Part Description: Part Type Resistance Tolerance TCR (if not standard) Example: S-4 100 OHM 1% For non-inductive windings (Resistance > 0.1Ω) insert the letter “N” (i.e. SN-4) 1 Below 0.1Ω the inductance of a single winding, or the metal element (SL) is negligible Riedon Inc. 300 Cypress Avenue Alhambra CA 91801 (626) 284-9901 (626) 284-1704 © Riedon, Inc. www.riedon.com sales@riedon.com Revised: 201810_003
