Vishay Beyschlag
Trimmable Flat Chip Resistors
FEATURES
• Designed for state of the art laser trimming
• Enables economical functional circuit adjustment
• Low TCR 50 ppm/K available
• Excellent stability ≤ 0.25 % (1000 h rated power at 70 °C)
• Wide ohmic range: 10 Ω to 1 MΩ
• Lead (Pb)-free solder contacts
• Compliant to RoHS directive 2002/95/EC
TCT 0603, TCU 0805 and TCA 1206 trimmable flat chip
resistors are best suited whenever stable circuit adjustment
is required and potentiometers will be either too expensive,
too unstable or too large. The trimming is done directly on the
printed-circuit board (PCB) using a state of the art laser
trimming system e.g. with YAG or CO2 laser source. Typical
applications include any type of electronic sensors,
oscillators or electronic circuits which have to be trimmed to
certain functional parameters after PCB assembly.
APPLICATIONS
• Electronic sensors
• Oscillators
• Electronic circuits

Notes
(1)
The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded.
All given figures are valid for the untrimmed resistor

•
These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over
operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.
