Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)

High Voltage with Flexible Termination System, X7R Dielectric, 500 – 3,000 VDC (Commercial & Automotive Grade)

Application Note

X7R dielectric is not recommended for AC line filtering or pulse applications. These capacitors and/or the assembled circuit board

containing these capacitors may require a protective surface coating to prevent external surface arcing.

Qualification/Certification

Commercial Grade products are subject to internal qualification. Details regarding test methods and conditions are referenced in

Table 4, Performance & Reliability.

Automotive Grade products meet or exceed the requirements outlined by the Automotive Electronics Council. Details regarding test

methods and conditions are referenced in document AEC–Q200, Stress Test Qualification for Passive Components. For additional

information regarding the Automotive Electronics Council and AEC–Q200, please visit their website at www.aecouncil.com.

Environmental Compliance

Lead (Pb)-Free, RoHS, and REACH compliant without exemptions (excluding SnPb termination finish option).

Electrical Parameters/Characteristics

Parameters/Characteristics

Operating Temperature Range

-55°C to +125°C

Capacitance Change with Reference to +25°C and 0 VDC Applied (TCC)

±15%

Aging Rate (Maximum % Capacitance Loss/Decade Hour)

3.0%

Dielectric Withstanding Voltage

150% of rated voltage for voltage rating of < 1,000 V

120% of rated voltage for voltage rating of ≥ 1,000 V

(5 ±1 seconds and charge/discharge not exceeding 50 mA)

Dissipation Factor (DF) Maximum Limit @ 25ºC

2.5%

Insulation Resistance (IR) Limit @ 25°C

See Insulation Resistance Limit Table

(500 VDC applied for 120 ±5 seconds @ 25°C)

Regarding aging rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.

To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.

Capacitance and dissipation factor (DF) measured under the following conditions:

1 kHz ± 50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 µF

120 Hz ± 10 Hz and 0.5 ±0.1 Vrms if capacitance > 10 µF

Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known as

Automatic Level Control (ALC). The ALC feature should be switched to "ON."
