Thick Film Power Ceramic Resistors
What's Thick Film Power Ceramic Resistors?
Thick Film Power Ceramic Resistors have displayed several key advantages in demanding high voltage situations, including both continuous-wave and pulse applications. These include radar and broadcast transmitters, x-ray systems, defibrillators, lasers, and high voltage semiconductor process equipment applications, where resistors must handle peak voltage anywhere from 20 to 80 kV. Typical applications include current limit in capacitor charge/discharge, crowbar, and tube-arc circuits. In these uses, Thick Film Power Ceramic Resistors provide low inductance, high average power per unit size, stability at high voltage, and durability at extreme peak-power levels. ◆ resistance range: 10 Ω ~ 1000m Ω ◆ allowable deviation: ± 1% ~ ± 10% ◆ temperature coefficient: minimum ± 50ppm (25 ℃ ~ 105 ℃) ◆ insulation withstand voltage: > 1000VDC ◆ insulation resistance: ≥ 10g Ω ◆ working temperature range: - 55 ℃ ~ + 225 ℃ ◆ maximum working voltage: 48kvdc ◆ inductance: non inductive ◆ connectors: tinned iron cap ◆ resistance installation: Welding ◆ overload: 5p value does not exceed 1.5umax5s, Δ R≤±0.2%R ◆ service life: rated power 1000h, Δ R≤±0.5%R ◆ steady state damp heat: mil-std-202, method 103, condition D, Δ R≤±0.4%R ◆ thermal shock: mil-std-202, method 107, condition C, Δ R≤±0.2%R Applications: Motor drive circuits Snubber circuits Bleeder Capacitor charge/discharge High-frequency circuits Impulse generators High-voltage circuits X-ray equipment High voltage power supplies Laser/Imaging equipment Capacitor charge/discharge RF dummy loads Dynamic braking Transformer protection For more information ,Please refer to "Thick-Film-Hybrid-Circuit" |
