Aluminum Housed Surface Mount Resistor - General Purpose/Precision High Power Resistor KAL

Product catalog summary

Overview: The KAL Series by Stackpole Electronics, Inc. features aluminum housed surface mount resistors designed for optimal heat dissipation. These resistors are available in power ratings from 5W to 250W and are RoHS compliant and lead-free.

Features:

Aluminum housing for maximum heat dissipation
Complete welded construction
Tinned copper terminals ranging from 5W to 50W
Centerless ground steatite or alumina cores
Molded epoxy body for enhanced heat transfer
Non-inductive winding available
Threaded terminals for 100W to 250W models

Electrical Specifications:

Dielectric withstanding voltage varies by model, with a maximum of 3,000 VAC for certain models
Temperature coefficient ranges from ±100ppm to ±20ppm depending on resistance value

Performance Characteristics:

Short time overload: 5x wattage rating for 5 seconds with a resistance change (∆R) of ±(0.5% + 0.05Ω) MAX
Moisture resistance: Tested at 40ºC with 95% humidity for 500 hours, resulting in ∆R ±(0.5% + 0.05Ω) MAX
Load life: 1.5 hours ON, 0.5 hours OFF for 1000 hours, resulting in ∆R ±(1.5% + 0.05Ω) MAX

Mechanical Specifications: Detailed dimensions are provided for various models, with tolerances specified in both inches and millimeters.

Ordering Information: The ordering code includes the product series, power rating, tolerance, resistance value, and packaging type. For example, KAL10FB10K0 represents a 10W resistor with 1% tolerance and a resistance value of 10K ohms.
