LC0402A103JT: DC – 6GHz Super Low Loss 0.01µF Capacitor
The DC block and de-coupling capacitors are critical for the performance of a RF/Microwave circuit or module.
Engineers are challenged to find the best capacitors for their design.
A wide band DC block capacitor with minimum insertion loss and the highest self-resonance frequency are essential for
any amplifier or other active circuits. Also, for a de-coupling capacitor in an active DC bias circuit, the DC bias point
needs to be as close to “high frequency ground” as possible throughout the frequency band.
Why LiConn LC0402A103JT? Ultimate combination of superior performance and lowest cost.
Performance: Insertion Loss and Return Loss Comparison
LiConn’s state-of-the-art capacitors address these challenges. Fig. 1 and Fig. 2 compare the insertion loss and return
loss of brand name capacitors with those from LiConn. The capacitors used in the graphs are 0402 size and 0.01uF of
the X7R series.

LiConn’s LC0402A103JT offers the best insertion loss throughout the frequency band up to 6 GHz. At 4 GHz,
LC0402A103JT introduces only 0.05 dB insertion loss while other products introduce more than 0.1 dB insertion loss.
The AVX has largest insertion loss.
The measurements are based on the thru test method. The capacitors are soldered in series on a 50 Ohm through line.
Performance: Voltage Rating
LC0402A103JT offers the highest voltage rating at 50V.
Application Example 1: For the input DC block of a low noise wide band amplifier chip, LiConn’s capacitor at 4 GHz
will have a 0.1 dB better noise figure than other capacitors being used for the same LNA chip. It will have more than a
0.2 dB better noise figure than other capacitors at 6 GHz.
Application Example 2: Due to the lower insertion loss of LiConn’s capacitor, the “high frequency ground” is better
and thus better grounding for a DC path for an active device. Using several de-coupling capacitors is not needed.
Cost: LiConn’s capacitors cost a fraction of their competitors. With LiConn’s capacitors, expensive large value
microwave capacitors are not needed.
