TCH35P20R0JE - Ohmite

TCH35P20R0JE Frequently Asked Questions (FAQs)

• What is the thermal resistance of the TCH35P20R0JE?
  The thermal resistance of the TCH35P20R0JE is typically around 10°C/W, but this value can vary depending on the specific application and mounting method. It's recommended to consult with Ohmite's technical support or refer to the manufacturer's application notes for more information.
• Is the TCH35P20R0JE suitable for high-frequency applications?
  The TCH35P20R0JE is a thick-film resistor, which can exhibit some high-frequency limitations. While it can be used in high-frequency applications, it's not the best choice. Ohmite recommends using their thin-film resistors, such as the TCH series, for high-frequency applications above 100 MHz.
• Can I use the TCH35P20R0JE in a high-temperature environment?
  The TCH35P20R0JE has a maximum operating temperature of 155°C, but it's recommended to derate the power rating above 125°C. For high-temperature applications, Ohmite offers other resistor series, such as the HVC series, which can operate up to 200°C.
• Is the TCH35P20R0JE compatible with lead-free soldering?
  Yes, the TCH35P20R0JE is compatible with lead-free soldering. Ohmite's resistors are designed to meet the requirements of the RoHS directive and can be soldered using lead-free soldering processes.
• What is the recommended land pattern for the TCH35P20R0JE?
  The recommended land pattern for the TCH35P20R0JE can be found in Ohmite's application notes or on their website. The land pattern should provide a minimum of 0.05 inches (1.27 mm) of clearance around the resistor body to ensure proper heat dissipation and to prevent electrical shorts.
