Cool-Pad CPR7154 thermal interface material dispenses like a thermal pad, but is said to show characteristics of a grease or gel when device temperatures increase to above 45°C.
Vishay Intertechnology has released the RCA-SR e3 series AEC-Q200 qualified standard thick film chip resistors designed for sulfur-containing environments. Offered in 0201, 0402, 0603, 0805 and 1206 case sizes, the devices provide resistance values from 10Ω to 10MΩ, including 0Ω jumpers, with tolerances of ±1% and ±5% and TCR of ±100ppm/K and ±200ppm/K. The resistors are rated for power up to 0.25W and operating voltages from 30V to 200V, with an operating temperature range of -55°C to +155°C. The series meets ASTM B809-25 sulfur resistance testing with a maximum resistance drift of 1% after 1000 hours at 60°C and specifies ΔR/R ≤ 1% after 1000 hours of rated power at 70°C. The devices feature a protective coating for environmental protection and pure matte tin terminations compatible with lead-free and lead-containing solder processes.
Vishay Intertechnology has released four new power inductors in 0806 and 1210 case sizes, expanding its IHLL (commercial grade) and IHLP (AEC-Q200 automotive grade) portfolios. The IHLL-0806AZ-1Z and IHLL-1210AB-1Z, along with the automotive-qualified IHLP-0806AB-5A and IHLP-1210ABEZ-5A, support inductance values from 0.22µH to 4.70µH with typical DCR as low as 6.6mΩ. The devices operate up to +165°C. The inductors use a composite powdered-iron construction that fully encapsulates the windings. Automotive versions feature side-plated terminations to support solder fillets and inspection, while commercial versions use bottom-only terminations.
