Case: TO-220 High Temperature Plastic Frequency Conversion High Frequency Balancing Snubbers Current Limiters Industrial Controls SHORT PRODUCT APPLICATION NOTE SWRP35-1001-1% TO220 series are high precision and high power resistors encapsulated in the TO-220 package. Power resistors are manufactured in 35 Watts. Resistance element is electrically insulated from metal heat sink mounting tab. When properly mounted Semiconwell's SWRP35-1001-1% TO220 packaged power resistors provide up to 35 watts of steady state power. These very low inductance resistors are ideal for many industrial applications: power supplies, power controls and inrush/bleeder resistors. Semiconwell thin film power resistors are manufactured by depositing continuous and defect free metallic films conferring long-term stability, very low TCR, very low current noise and negligible non-linearity. Semiconwell thin film power resistors are price competitive while outperforming the thick film power resistors currently used in high power applications. For more info as how thin film resistors compare with thick film resistors, see SWAN04. SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION Integrated passive networks are manufactured using advanced thin film technologies including ultra-stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film resistor technology is the preferred solution for all applications that require low noise, long-term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1 W/sq to 10,000 W/sq. All Semiconwell's products are available in die form and as KGD, known good die and are ideal for high reliability hybrid and multi chip module applications. Besides thin film resistors, Semiconwell integrates capacitors, Schottky diodes, Zener diodes and transistors. Integrated passive and active networks are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diodes to provide complete standard and custom RCD solutions. In die form, these products are ideal for hybrid and multi chip module applications. In packaged form, these products are the best solution where space and weight are a concern.
