The EMK316BB7226ML-T from Taiyo Yuden is a 22µF multilayer ceramic capacitor (MLCC) with a 16V DC voltage rating in a 1206 (3216 metric) package. The X7R dielectric provides capacitance stability of ±15% over the -55°C to +125°C operating range. The high 22µF capacitance in a compact 1206 footprint makes this device ideal for SMPS filtering, power supply bypass, and DC-DC converter output stabilization where bulk capacitance is needed in a small footprint. The low ESR of MLCC construction provides effective high-frequency noise suppression compared to aluminum or tantalum capacitors. The M tolerance (±20%) is standard for high-value X7R MLCCs. The device is RoHS compliant and compatible with lead-free reflow soldering.

The EMK316BB7226ML-T operates as a passive capacitive element:

1. MLCC Construction: Multiple layers of barium titanate ceramic dielectric are interleaved with nickel inner electrodes. The 22µF capacitance is achieved through the high dielectric constant of X7R ceramic combined with hundreds of thin dielectric layers, maximizing electrode area within the 1206 package volume.

2. X7R Characteristics: The ferroelectric X7R dielectric provides high volumetric efficiency but exhibits temperature-dependent capacitance variation (±15% over -55°C to +125°C) and DC bias dependence. At rated 16V DC, the effective capacitance may be 40-70% of the nominal value due to ferroelectric domain saturation. This must be considered in circuit design.

3. Decoupling Function: In power supply applications, the low ESR (typically <10mΩ) and low ESL of the MLCC provides effective bypass of high-frequency switching noise (1MHz-1GHz). The 22µF value provides bulk energy storage for load transients, complementing smaller value MLCCs that handle higher frequency components.

Pin Nombre Tipo Función
1 Terminal 1 Passive Capacitor terminal (no polarity)
2 Terminal 2 Passive Capacitor terminal (no polarity)
  • SMPS output: 22µF at 16V stabilizes DC-DC converter output rails (3.3V/5V/12V) with low ESR for fast transient response and low output ripple
  • IC decoupling: 22µF bulk capacitance near FPGA/ASIC power pins handles load transients during switching activity; complements 0.1µF/0.01µF MLCCs for full-spectrum decoupling
  • Audio bypass: Low ESR MLCC provides clean power supply bypass for audio CODECs and amplifiers, reducing power supply induced distortion
  • Portable devices: 1206 package with 22µF replaces larger tantalum capacitors in smartphones and tablets, saving PCB area while providing equivalent bulk capacitance
