TT Electronics SIL Resistor Network L Series Datasheet

Category: Electronics, Resistors, TT Electronics PLC

Overview

This datasheet pertains to the L Series Thick Film Low Profile SIP Conformal Coated Resistor Networks from TT Electronics, which are compliant with the RoHS3 standards, being lead-free and adhering to the EU Directive 2011/65/EU as amended by (EU) 2015/863.

Electrical Specifications

Resistance

The resistors come in ranges of 1% tolerance (22R to 1M ohms), 2% tolerance (10R to SM6), and 5% tolerance (10R to 10M ohms). Custom options for tolerances of +1% (F Tol) and +5% (J Tol) are also available. The network offers a standard resistance tolerance noted at 25°C and an operating temperature range from -55°C to +125°C.

Temperature Coefficients and Power Ratings

Temperature Coefficient of Resistance (TCR) varies according to resistance value, being ±100ppm/°C for values under 50 ohms and ±250ppm/°C otherwise. TCR tracking is specified at +50ppm/°C. Each resistor element in circuits -1 & -5 has a power rating of 125mW, and those in circuit -3 are rated at 200mW at 70°C.

Voltage and Insulation

The maximum operating voltage is either 100Vdc or the voltage per resistance (VPR), with an impressive insulation resistance of 10,000 Megohms.

Environmental and Mechanical Performance

A series of tests were conducted to examine the resilience of the resistor networks under various conditions. The tests included Thermal Shock plus Power Conditioning, Short Time Overload, Terminal Strength, Moisture Resistance, Mechanical Shock, Vibration, Low Temperature Storage, High Temperature Exposure, and Load Life of 1,000 Hours, with a ΔR (change in resistance) ranging from 0.25% to 1.00% illustrating their durability.

Additional Qualifications

The networks have also been tested for Resistance to Solder Heat, Dielectric Withstand Voltage, and Marking Permanency. Their flammability rating complies with UL-94V-0, and the units are proven to sustain a storage temperature range between -55°C to +150°C.

Quality Assurance and Standards

While the datasheet indicates that the resistor networks meet various MIL-STD-202 methods, the final note clarifies that specifications are subject to change without notice and that TT Electronics holds the right to make alterations to product specifications. Although information provided is believed to be accurate for current production, the final recommendation is to check TT Electronics’ official data for any updates before application.
