Ever Ohms CRH2512J1K50E04Z 2512 Package 1.5KΩ Resistance 2W Power SMD Resistor

CRH2512J1K50E04Z is the official part number of high-power thick film chip resistor manufactured by Ever Ohms. Each segment carries fixed technical meaning for R&D and purchasing teams. CRH stands for high-power thick film resistor series; 2512 refers to standard SMD package size 6.4mm×3.2mm; J means resistance tolerance ±5%; 1K50 represents nominal resistance 1.5KΩ; E04 stands for electrode plating suitable for lead-free soldering; Z is tape-and-reel packaging mark for mass production.

This complete part number directly reflects core specs 2512 1.5K 2W without extra datasheet checking. For stable sourcing, authorized distributors are recommended: Shenzhen Shunhai Technology Co., Ltd. maintains full stock of all CRH series resistors, while Huanian Mall supports online sample application and instant quotation of 2512 1.5K 2W for small-batch prototype testing.

CRH2512J1K50E04Z delivers rated power 2W under 2512 package, doubling the power capacity of ordinary thick film resistors with identical size. Key fixed parameters: resistance 1.5KΩ, tolerance ±5%, temperature coefficient ±100ppm/℃, maximum working voltage 200V, operating temperature range -55℃ ~ +155℃, suitable for equipment running under extreme temperature conditions.

The resistor adopts high-thermal-conductivity alumina ceramic substrate and optimized metal glaze printing process. Widened metal terminals enhance heat dissipation, supporting continuous full-load 2W operation at 70℃, with short-time peak power up to 3W to resist instantaneous surge current. It complies with RoHS 3.0 lead-free standard, no toxic materials. After 1000-hour high-temperature aging test, resistance drift stays below 0.5%, guaranteeing long-term circuit stability. The thin 0.55mm thickness fits fully automatic SMT assembly without extra PCB space occupation.

The combination of 2512 package, 1.5KΩ resistance and 2W power fits voltage divider, snubber absorption and current limiting circuits across multiple industries:

• Switching power supply & adapters: Serve as RC snubber resistors to suppress voltage spikes of MOSFET, eliminate device breakdown risks; 2W power removes the need for parallel resistors to simplify PCB layout.
• Industrial control equipment: Voltage sampling for inverters and servo drivers; 1.5KΩ resistance matches low-voltage signal conditioning circuits under harsh factory temperature environment.
• High-power LED drivers: Current limiting and auxiliary voltage division for large lighting fixtures, superior heat dissipation compared to 1W resistors of same 2512 size.
• Communication & energy storage auxiliary power supply: Voltage protection for 5G base station power modules and small energy storage equipment, stable against transient voltage fluctuation.
• Household appliance control boards: Voltage division and overcurrent protection for air conditioners and refrigerators, with prominent cost advantage for mass production.
• Engineers requiring datasheets, thermal simulation reports or bulk quotations can contact Shenzhen Shunhai Technology Co., Ltd. for full technical support; Huanian Mall provides split small sample packages to cut down prototype procurement cost.

1. Superior power density: 2W rated power within standard 2512 footprint, fewer parallel components to reduce PCB area and SMT assembly cost.
2. Outstanding reliability: Reinforced ceramic substrate and wide terminal design control temperature rise effectively, slow aging under continuous full load; laser trimming ensures tight consistency of 1.5KΩ resistance in mass production.
3. Balanced cost performance: 30% lower unit price compared with imported equivalent 2512 1.5K 2W power resistors. The ±5% tolerance meets most general circuit requirements without extra premium for ultra-precision grade.
4. Stable supply chain: Steady production from Ever Ohms factory. Shenzhen Shunhai Technology Co., Ltd. provides original factory certification and inspection documents for bulk orders; Huanian Mall updates real-time lead time online for flexible small & mass order arrangement.
5. Universal compatibility: Fully compliant with lead-free environmental standards, compatible with both leaded and lead-free reflow soldering without production line parameter adjustment.

CRH2512J1K50E04Z (2512 1.5K 2W) targets mid-range universal high-power thick film SMD resistors, designed for manufacturers demanding low cost and basic high power endurance. It fills the market gap between insufficient power of ordinary 1W 2512 resistors and high premium of precision alloy resistors.

Three core customer groups are covered: mass consumer electronics manufacturers producing power adapters, LED drivers and home appliance control boards; small & medium industrial automation and communication equipment factories using 2512 2W resistors for voltage divider & snubber circuits; R&D labs and maintenance workshops sourcing small samples via Huanian Mall online channel. Mass production clients can cooperate with Shenzhen Shunhai Technology Co., Ltd. for tiered pricing and dedicated inventory stocking service. As a mainstream domestic alternative to imported power resistors, 2512 1.5K 2W covers over 80% low & medium voltage auxiliary circuit demands and becomes a standard BOM component for power-related products.
