Part Marking
Thermopads are marked with attenuation value and temperature coefficient of attenuation code as follows:
Note: TVA – W1, HTVA, MTVA – W1, WB1 and G units not marked.
Configuration Code
CTVA, KTVA, 42TVA
Metallization Options
• Planar (no code)
• Triple Wrap (W3)
• Single Wrap (W1)
• Pretinned (S)
• Lead Free (F)
• Single Wrap (WB1) Metallization wraps around ground terminal only. Full backside metallization. Input and output
• Gold (G)
Note: KTVA has backside ground metalization. Input and output terminals have gold metalization for wire bonding.
Example: P/N TVA0300N07W3S is TVA configuration code, 3 dB nominal value at +25 °C, negative shifting
thermopad with TCA of 0.007dB/dB/°C, triple wrap with pretinning.

Attenuation
Planar device for flip chip mounting offers the best RF performance and lowest cost.
Metallization wraps around input, output, and ground terminals. Permits inspectable solder
fillets when flip chip mounting.
Metallization wraps around ground terminal only. Full backside metallization.
Pretinning (with Sn 62) improves solderability (available on all of the above options except
Option G and KTVA).
Lead free, pure tin plating options are available (excludes WB1 and G metallization options).
terminals have gold metallization for wire bonding (MTVA series only).
Planar device with gold metallization. Typically used for wire bonding (MTVA and HTVA
series only).
